Does the average bloke [or blokette] with an internet connection even know what 'legal porn' for UK citizens is
in this era of slightly less draconian censorship and obscenity legislation...???

Yes.. we all know what the most 'highly illegal' is.. and damn right it should be..

But it's those tricky grey areas of hesitation and uncertainty.....?????

Then there's that sanitized middle class middle-brow 'sensual erotica':
and weird studenty arty farty nudey stuff in Art Gallery Exhibitions...?????
